AQR113c does not correctly report its supported PMA capabilities which includes speeds like 10G/5G/2.5G. Add get_features() to explicitly declare 10G/5G/2.5G/1G support instead of relying on PMA register reads. Signed-off-by: Hongmei Xu <redacted> --- Changes in v2: - Fix subject prefix to [PATCH net-next] - Limit scope to AQR113C only as AQR113 not tested - Link to v1: https://patch.msgid.link/20260923-net-phy-aqr113c-fix-pma-capability-v1-1-497359310f06@oss.qualcomm.com --- drivers/net/phy/aquantia/aquantia_main.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
